Early on, before we knew how well the vaccines worked, it wasn't unreasonable to question their efficacy.
That was a lot of studies ago.
Here are two more quality studies just published in the NEJM.

At this point the data is totally overwhelming. The vaccines are safe and effective. The fake experts on FAUX NEWS were all wrong.
If you are a regular viewer, as I used to be, you have been duped. If you believed what the doctors of disinformation said on Tucker, Laura or Hannity, you fell for it.
The doctors of disinformation are lacking. They lack the requisite training. They (in several cases) are not even licensed MDs. But mostly, they lack quality data.
They lack evidence upon which to base their claims the vaccine is ineffective, dangerous and should be pulled from the market.
If you are still clinging to their claims after so much data has been published refuting them, you are really delusional.
The first study at NEJM compares effectiveness of the monovalent product during the 99-day interval from 5/25/22 to 8/31/22, vs. the effectiveness of the bivalent product during the interval from 9/1/22 to 12/8/22.
So it's a comparison of summer vs fall seasons; and the dominant strains were completely different. How is this supposed to be convincing? What sort of "experts" would design such a study, and what sort of peer reviewers would allow it to be published?
